Do UFOs / Extraterrestrials exist?

Wasn't there an experiment where various individual elements were mixed (carbon, oxygen, hydrogen, nitrogen...) and extreme conditions were created (using electrical charges I think), and the end-result were biomolecules?

I posted this in NTO, officially hijacking that thread so I figured it probably belongs here.

I have no doubt there is life out there, but logic tells me that aliens have probably never visited earth (im hoping and wishing this logic is wrong ). We are one small planet thats part of a one small solar system in the far reaches of one small galaxy called the Milky Way. In 1999 the Hubble Space Telescope estimated that there were 125 billion galaxies in the universe, and in May 2009 hubble was fitted wia a new camera and has now observed 3,000 visible galaxies, which is twice as much as they observed before with the old camera. We're emphasizing "visible" because observations with radio telescopes, infrared cameras, x-ray cameras, etc. would detect other galaxies that are not detected by Hubble. As observations keep on going and astronomers explore more of our universe, the number of galaxies detected will increase.

That makes us a needle in the proverbial haystack! But I hope im wrong and all this static we spew from our planet has garnered someones "oops" somethings attention.

well there is a theory that all the water ( or the majority ) on our planet came from an ice comet. Along with it came Microorganisms that eventually evolved to become us. That would mean that, all of us, including all the plants and animals are alien to our planet.

But there was a problem with that theory. All of the comets astronomers observed were indeed packed with water ice, but a lot of it was what's known as heavy water, in which the hydrogen in the H2O mix is an isotope known as deuterium, with one proton and one neutron in its nucleus. The hydrogen found in ordinary water has no neutron. Since the overwhelming share of the water in earth's oceans is made with the light hydrogen atom, astronomers calculated that comets could have accounted for only about 10% of what's there. Now, according to a new paper published in the journal Nature, it appears that those scientists may have been wrong — and the reason for their error is that they were simply looking at the wrong comets.

The paper, co-authored by researchers at the California Institute of Technology, is based on observations conducted by the Herschel Space Observatory, a spacecraft launched by the European Space Agency in 2009. Herschel looked specifically at comet Hartley 2, a small comet discovered in 1986 with an estimated diameter of .75 to .99 mi. (1.2 to 1.6 km). Analyzing the chemical composition of Hartley 2's corona — or the gassy veil surrounding the main comet body — Herschel discovered that its concentration of heavy water was only about half that of any comets observed before. While that wouldn't entirely explain earth's particular heavy- and light-water mix, it does bring the chemistry a lot more into line — and gives the cometary explanation for earthly water a big boost.

Im with you on that LHK. I feel it's unrealistic and egotistical to think that Aliens would look like humans. I have no doubt there is life out there, but logic tells me that aliens have probably never visited earth (im hoping and wishing this logic is wrong ).

I don't think people assume aliens will only be humanoid; more so, that it's just one of many possibilities and the most intriguing one.

I don't think it's egotistical or unrealistic, check this out:

I had come across something that looks at this question and it's related to something called "convergence". This idea was also related to "Jon Conway's" Game of LIFE, http://www.bitstorm.org/gameoflife/, which consists of a collection of cells which, based on a few mathematical rules, can live, die or multiply. Depending on the initial conditions, the cells form various patterns throughout the course of the game.

Now the jist of this convergence is, if evolution is going on on other planets, then what the end results of these (what they call laws) are, are that the most complex most "advantageous" adaptations are occurring. "These laws constrain evolution", which causes re-occurring patterns to happen. Thus one assumes that eyes develop for sight, legs for walking etc. So evolution could perhaps be discovering the same solution to the curves that nature throws at it elsewhere, bipedalism would be one such solution.

well there is a theory that all the water ( or the majority ) on our planet came from an ice comet. Along with it came Microorganisms that eventually evolved to become us. That would mean that, all of us, including all the plants and animals are alien to our planet.

Panspermia proposes that life forms that can survive the effects of space, such as extremophiles, become trapped in debris that is ejected into space after collisions and survives to land on other planetary bodies.

I believe I saw a UFO once, but I don't like to tell anyone about it because it sounds pretty crazy. The only people that know about it are my three friends that were with me and a couple other of our friends. After it happened, we kind of agreed not to talk about it and we only told a couple of our friends. I want to share my story with you guys, but whether you believe me or not doesn't really matter to me. I swear that it happened and I have to admit it was one of the scariest moments of my life.
Last summer me and my friend Alex were chilling on his dock in his backyard while my friends Frankie and Steve were rolling a blunt in the shed. We were looking up at the stars and we so this round bright light over the water that looked kind of like an airplane, but it wasn't moving. We were talking about it and trying to figure out what it was when suddenly it got even brighter. Then it shined a beam of light across the water directly at us. Thinking back on it, that "beam of light" might have just been a reflection of it over the water, but that is not where it ends. As we start to freak out, the thing starts flying up and to the left slowly. Then it suddenly flies really fast in the opposite direction and disappears. We were in disbelief at what we just saw and we ran over to the shed to tell my friends Frankie and Steve. They laugh at us and think we are full of sh*t, but we swore that we saw it.
So we went back to the dock so they could smoke their blunt and we were just chilling looking at the stars again. That was when we noticed two more of the bright lights just floating like 300 feet above the water about where we saw the other one. It was about a mile away and it wasn't moving. Frankie and Steve are still not convince it is anything yet they think it's a helicopter or something, so they just continue smoking their blunt as we stare at the two lights. The one on the left started getting brighter and the "beam of light" came across the water again and stopped right at us. We started freaking out, but we didn't want to leave. Then, I sh*t you not, the one on the right started shooting red lasers up to the left of it and that was when a third light suddenly appeared. Now I was basically sh*tting my pants and I wanted nothing more thatn to get out of there, but Frankie and Steve wanted to finish their blunt, so we stayed. The bright one on the left then flew up and to the left about the speed of an airplane and disappeared. The other two lights got brighter and the lower one took a similar flight pattern as the first one me and Alex saw and disappeared. That left just the one bright light that appeared after the lasers. Suddenly it started flying towards us, but not as fast as the other ones flew. I freaked out and ran to my car and my friends ditched their blunt and were right behind me. We got to my car and before we got in we saw that light fly over our heads like 500 feet above us and that was the end of that.
We sat in my car and talked about it for the rest of the night. The only logical thing that we could think of it being was a UFO. We knew that no one would believe us if we told them, so we agreed to just keep it to ourselves. We only told our closest friends about it. We tried to film it on our phones, but it was too dark to see anything and the only thing you hear in the video is us freaking out, which was actually kind of funny to watch afterwards. I'm sure most of you will think I'm full of sh*t, but I swear on my life it happened and I have three friends to back me up.

What grabbed me from your story was the beam of light. Did you get the impression that whatever it was, knew you guys were thinking about it ??

Here's "one" of mine. (condensed)

Back around the spring/summer of 2004ish(?) I was laying on my couch watching the tube. Anyways a commercial comes on and I roll my head over to look out a large window that my couch is under. Looking out at a clear black sky with the odd big puffy cloud hanging around. Small town with no light pollution.

So this "speck of light" catches my eye as it's moving across the night sky. I'm curious, get up, go outside find this "speck of light" again at which point I decide to sit on my porch and continue to watch it. I watch this thing travel in a straight line for a fair period of time NW to SE. While doing so it also travels above one of these puffy clouds and comes out the other side and continues till I can no longer see/get bored with it.

During this time I guess it must be a satellite perhaps. So I'm bored go back inside and back to the couch/tube again.

A while later, same thing, turn my head over to look outside and there's this bright, kinda golden, wavy almost liquidish light shining directly at me. The very instance I noticed the light it seemed to retract into a "speck" in the sky, like it didn't just blink out. It was different than that, it retracted.

I jump up from the couch and exclaim WtF !! Run out to the porch, look around, find this speck of light in the sky. This time it's traveling in the opposite direction, straight line and that was that.

Firstly, the thing that stood out was how the shining light retracted the split second I noticed it, like as soon as it became a thought in my head. Then just in the way it retracted as opposed to blinking out, and then the tangibility of the light, like I said it was like a liquid. And of coarse how it was shining directly at me for whatever reason. I was left with the impression that whatever it was, knew I was watching it and returned the favor so ta speak.

If there were beings so advanced that they could travel between planets, I don't see why they wouldn't be willing to show themselves to us. We're not even a class M planet. They would in all likelihood be able to destroy us with ease, let alone defend themselves from us. They would/should have no reason to fear us.

Perhaps, because they've done that previously to other inhabited worlds and then they watched it all go to hell in a hand basket and thought, man did we f--- up.

One theory that I like to think of, that WOLF mentioned earlier was the one of, what if it's us from the future. When you think about it it seems to answer that question; although, I'll admit that ones pretty far out there on the imagination scale. I have an easier time believing in other biological entities on their own timeline than humans travelling around in time.

Maybe we're just one big experiment for them and they don't want to contaminate the results to any great extent.

The Earth as a biosphere could be a big petri dish for developing Genes.

I saw a UFO once. In retrospect, I realize it was almost certainly just a meteor (but an awesome one). I think I was around 10-12 at the time. It was intensely bright, and shot across the sky, I was in the car in the back seat, staring out into the sky randomly at the corner of Burnhamthorpe and Cawthra in Mississauga, Ontario Canada.

I rather like the concept of Panspermia. Whether or nor we in particular are a result of it, it seems to make some good sense. A little evidence (like bacteria on Mars with a compatible DNA sequence) would be nice.

Maybe they don't have emotions and are just beings of pure logic. They just want to observe us and try to understand, us rather than conquer us, and maybe they think we are not ready to meet them yet.

The thing with Panspermia is we're still talking vast distances, I would think. Whereever these building blocks originated they would have to survive the whatever sent them on their way, then travel incredibly far to make it to their destination. The caveat here is the Universe has been around a long time, so it's still plausible.

The thing is, people mention that they don't think we've been visited by intelligent beings, because of these distances involved, light years. I still think that a super intelligent civilization has possibly mastered these distances. We ourselves went from kitty hawk to the surface of the moon in a hundred years. So why couldn't a super intelligence with perhaps 100s of thousands of years of advacncing civilization over ours have found a way.

Intelligence moves faster than nature, for lack of a better description. Look what we've done with dogs. I'm open to both ideas, Panspermia and extraterrestrials travelling threw vast distances.
